I checked out FeedRinse, FiltermyRSS, and FeedSifter and decided to go with the Feed Rinse. I signed up for a Feed Rinse account - but only after signing up realized that I won't use this tool now that I have it! I don't really use my bloglines account very much. I don't have a lot of time to check out the blogs that I get, although I would love to read them. One of my goals is to get into my bloglines and clean it up - we will see how long that really takes me. I went through my blogs and got them all organized in a way that should help me stay up on them. Working on THINGS again is giving me the chance to get to this.
Delicious is a great feature - I learned about it during 23 Things on a stick, but don't use it as much as I had anticipated I would when I first started out. I added all my favorites from school to delicious so that I know I can have access to the same information at school and at home.
I think that both the RSS and Delicious are great tools - I suggest Delicious to people all the time, because I know that finding sites is a pain and having a tool that makes that easy it awesome.
